GOVERNOR FOR COTTON-GINS.

SPECIFICATION forming part of Letters Patent No. 251,859, dated January 3, 1882. Application filed October 24, 1831. (No model.)

invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form part of this specification. I

My invention relates to an improvement in automatic regulators or governors for feeding attachments to cotton-gins, and is intended as an improvement upon the patent granted to me May 10, 1881; and it consists, first, in the combination of a movable roll-breast, an automatic regulating mechanism connected thereto, and means for suspending the roll-breast from above'so that it can move back and forth in relation to the frame according to the pressure in the roll-box; second, in the combination of a roll-breast which is movable in relation to the frame and suitable ropes or chains by which the breast is connectedto ashaft, thatis in turn attached to a suitable scale and slide by other ropes, which pass up and around pulleys arranged in amovable frame placed on the gin; third, in a movable frame which is adjustable upon the top of the gin and a rocking frame which is pivoted in the movable frame, whereby the amount of feed to the rollbox is regulated.

The object of thisinvention is to greatlysimplify and cheapen the construction, as shown in my former patent, and render the parts more easily adaptedto gins of different sizes and constructions.

Figure 1. is a plan view of my invention with the feeding attachment removed. Fig. 2 is a vertical section of the roll-breast, showing its attachment to the rope, wire, or chain. Fig. 3

is a side elevation of my invention complete.

Fig. 4 is a rear view of the machine. shows a modification.

. A represents the roll-box, which is of the usual construction, and B the roll-breast, which may either be made solid, as is here shown, or slotted, as shown in my former patent, for the Fig. 5

purpose of allowing the seed to freely escape. To each end of this roll-breast is secured a curved casting, O, which extends over the top of the roll-box, and which in some cases will be provided with a pulley, D, which will support the breastin position. Where the breast ismade specially for the gin this roller D will run upon the part E of the roll-box; bntwhere this construction cannot be utilized the rollbreast will be suspended from the frame F of the feeder by means of the rigid rod G and a short pivoted rod, H. This pivoted rod H allows thesame upward and'outward movement to the roll-breast that it has where it is suspended upon the rollers D. Where the castings G are specially prepared there are slots made in their rear ends just large enough to have the rollers D inserted, and then pivotal bolts are passed through the castings and the rollers. Where the rollers are to be used and the castings are notspecially prepared, they are simply pivoted to the sides of the castings.

Fastened to the inner end of each of the bolts, which serves as a pivot for the roller, is the rope, wire, or chain I, which has its rear-end fastened to the pulley J, that is secured to the shaft K, that is journaled on the rear of the gin-frame L. This shaft is placed in a small box, which is open at its rear side and extends the full length of the gin. To one end of this shaft is secured thedouble pulley M, from which run the two counter-extending ropes, wires, or ch'ains N, which have their up: per ends connected to a shaft,'O, upon which. are secured the pulleys P. From these pulleys I? run the cords Q B, one being fastened to a slide which is connected to the rear end of the dog S. The rope Q need not necessarily be wrapped around the pulley P, for the pulley may be used simply as a guide to the rope, as shown in Fig. 3 but where it is desired to give a quicker movement the rope N will be wrapped around the shaft and the rope Q will extend from the pulley.

. The rocking frame T is the same as shown in my former patent; but instead of being stationary upon the top of the gin, as is there shown and described, the frame is pivoted by an iron pin in the frame U, which is provided with a series of holes for the purpose of ad justing the frame up and down, so as to give a longer or a shorter movement of the pawl S. This frame U can be adjusted back and forth upon the top of the gin, as is required, and thus the machine is made more applicable to gins of different sizes and constructions. The frame T is rocked back and forth by the crank which is connected to the shaft of the drum V, and the wheel W, which is secured to one end of one of the'shafts over which the endless apron X passes, is operated by the dog S as the frame is made to rock back and forth, as described in my former patent. To the upright Y is fastened the dog Z, which serves to prevent any backward movementofthe wheel W.

This invention differs from the invention shown in my former patent in dispensing with a numberof parts there shown and making the parts adjustable, so as to be more readily applied to gins of different sizes. The whole operation of the machine, however, depends upon the pressure of cotton in the roll-box, as fully described in my former patent. The pressure in the roll-box is made to control not only the feeding of the gin, but the yielding of therollbreast enables the gin to carry a larger roll without choking or breaking the roll than it otherwise would do.

Having thus described my invention, 1 claim- I. The combination of aroll-breast, an automatic regulating mechanism connected thereto, and means for suspending the roll-breast from above so that it can move in and out in relation to the frame according to the pressure in 5 the roll-box, substantially as shown.

2. The combination of the roll-breast with the ropes I and shaft K, substantially as described.

' 3. The combination of the movable roll- 0' breast, the connecting-ropes I, the shaft K, provided with the pulleys JM,the scale and slide, and ropes which run from the pulleys M to the scale and slide, substantially as set forth.

4. The combination of the movable frameU 5 with the rocking frame T, which is pivoted therein, the frame U being made adjustable upon the top of the gin-frame, substantially as specified.

In testimony whereof I aflix my signature 50 f in presence of two witnesses.
